2. Christianity uniquely offers a non-performative identity--not constantly ebbing and flowing based on your accomplishment and conduct. (Phil 3:4-9; 1 Cor 4:3-4)
3. Christianity offers a basis for morality and justice that avoids the twin dangers of relativism and oppression. (I freely admit that many Christians use secular moral foundations and themselves veer toward relativism or oppression).
4. Christianity offers a kind of freedom (embracing the right restrictions) that, unlike the secular definition (the absence of restrictions), does not undermine love relationships.
5. Christianity offers a unique hope for the world--not eventual nothingness (secularism) and not even mere spiritual paradise (other religions). It promises a renewed, perfect physical world--a new heavens and new earth wherein dwelleth righteousness.
6. Christianity offers a resolution to guilt, shame, and self-laceration that avoids both minimizing your own failures and allowing other people to ultimately define you.
7. Christianity offers a unique view of power. The incarnation, death, resurrection, and ascension of Jesus shows us power both voluntarily relinquished and yet deployed for service to others.
8. Christianity offers a meaning and purpose in life that suffering not only cannot take away from you, but can only enhance. It can enable you to face death without any fear.
9. Christianity offers a unique account of morality/truth. Not subjectivism grounded in culture or evolution (secularism) nor objectivism grounded in an impersonal transcendent norm (Greek-Roman; idealism). Rather it is grounded in an absolute Person--Jesus. See L.Ferry, H.Bavinck.
10. Christianity offers a unique view of salvation. We are saved by sheer grace and Christ's work not ours. We cannot contribute to salvation with moral effort, religious observance, prayers, transformed consciousness, etc. A finished salvation is received, not achieved.
11. Christianity offers a unique approach to repairing relationships. It neither privileges the forgiven (so that justice is not done) nor privileges the forgiver (so forgiveness is withheld). Without both we can't maintain human social relationships. (Writing a book on this now.)
12. Christianity offers a unique view of uniqueness. The claim of uniqueness plays into the human need to feel superior. But Christianity's difference is the grace-claim: saved Christians are NOT better than anyone. That particular uniqueness can subvert the dangers of claiming it.
